WILLIAM A. MCGUIRE, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE MCGIIIRE MANUFACTURING COMPANY, OF SAME PLACE.

FREIGHT-CAR DOOR.

SPECIFICATION forming part of Letters Patent No. 436,586, dated September 16, 1890.

Application filed November 5, 1889. Serial No. 329,372. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM A. MCGUIRE, residing at Chicago, in the county of Cook and State of Illinois, and a citizen of the United States, have invented a new and useful Improvement in Freight-Car Doors, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation showing the door closed. Fig. 2 is a vertical section at line 2 2 of Fig. 1. Fig. 3 is a detail, being a horizontal section at line 3 3 of Fig. 1, showing the door nearly closed. Fig. 4 is a detail, being a section at the guide for the lower end of the door, showing the door closed. Fig. 5 is a detail, being a section through the locking-bar for the door. Fig. 6 is a vertical section through one cf the door-hangers. Fig. 7 is a similar view showing a modifica-g tion. Figs. 8 and 9 are details, being sections through one hinge of the locking-bar. Figs. 3, 4, 5, 6, 7, S, and 9 are enlarged.

This invention relates to doors for freightcars.

The objects of my invention are to provide improved devices for hanging and supporting the door, to provide-improved devices for fastening the door when closed, and to improve the construction and operation of freight-car doors generally, which I accomplish as illustrated in the drawings, and as hereinafter described.

That which I claim as new will be pointed out in the claims.

In the drawings, A represents the side of the car, and B the roof.

C represents a sliding car-door, which may be constructed in any of the usual or wellknown forms, except as to features hereinafter particularly described.

D is a T-rail secured to the eaves-board of the car, as shown in Figs. 1, 2, 6, and 7.

E E are two door-hangers adapted to slide on the T-rail D. Each hanger E may have a roller to run on the inner side of the T-rail D, as shown in Fig. 6, or it may have a slidshown in Fig. 7.

F F are two brackets-one for each hanger E-secured to the door, one near each upper corner, as shown in Fig. 1.` Each bracket F is provided with two ears, which project upward above the edge of the door C on each side of the hanger, and each ear is provided with a slot f, into which a pin e on the hanger projects, so that the door may be moved side- Wise on the hangers E.

G G are two guides-one near the top and one near the bottom of the door-which are 6o Secured to the door-post of the car, as shown in Figs. 1, 3, and 4, and which project outwardly and forwardly, so that when the door is shoved forward for the purpose of closing it its forward edge will engage with the g'uides 65 G and be moved sidewise on the hangers E, the edge of the door being rabbeted at the point of engagement with the guides G. The forward edge of the door, as shown in Figs.

3 and 4, is provided with a shoulder similarly 7o to that shown at the rear of the door, as in Fig. 5. This is the preferred form of construction, but it is not essential. The edge of the door is recessed or cut away on alevel to receive the guides G G and permit the door to passbeyond the vertical face of said guides, as shown in Fig. 4. The rear edge of the door is then to be pushed in on the hanger at the rear side of the door, so that the door will occupy the position shown in 8o Figs. 5 and 6; or, if desired, it maybe pushed in untilits outer sideis flush with the side of the car, as shown in Fig. 7.

The door C is provided with a shoulder h on its rear edge, as shown in Fig. 5, which allows the door to be pushed in a part of its width. An angle-iron II is placed on the shoulder h to protect the door. The door C is made somewhat narrower than the door- Way, so that a space will be left between the 9o inner edge of the door and the door-post, thereby avoiding any binding of the door from the sagging of the car. The forward edge of the door is provided with a beveled plug c, which enters an iron socket a, secured in the door-post, thereby holding the forward edge of the door against side movement when the door is closed. The rear edge of the door is held against the door-post, and the door is locked in its closed position bya'locking-bar roo J, which is hinged, as at I', to a bolt I, secured in the side of the car, as shown in Fig.

5. This bar .I is provided with a joint c' at such a distance from its point of attachment that it can be swung around against the side of thedoor When closed and bind the door against the door-post, as shown in Fig. 5. The joint or hinge t' is a loose hinge, as shown in Figs. 8 and 9, so that the outer end of the locking-bar J may be raised to pass over a staple 7' on the door C, by which the bar may be locked to the door. The outer end of the bar J is provided with a hook Z, which is adapted to enter a recess K in the side of the car and hold the bar J against the side of the car when the door is open, so that the bar Will not interfere With the door when being opened or closed. A groove 7c is provided in the side of the car for the bar J.

The door above described can be readily openedxand` closed, and when closed is held firmly in position, and at the same time the locking-bar binds it against the door-post,.so 4that no sparks from the engine can pass between it and the post. Theshoulder h gives 'the door two points of contact on each edge, one with the post and one with the stop m, as shown in Fig. 5.A

The locking-bar J -furnishes a very strong and reliable locking device, and, being placed at the rear of the door, is covered by thedoor when the door is open, so that it cannot catch or be caught by any object if the-car-is moved with the door open.

The guides G automatically throw in the `forward edge of the door When the door is closed, and the plug e holds the door firmly at themiddle of the front edge.

The hook Las shown in Fig. 2, is curved so that it will automatically be raised and enter the recess K in the side of .the car and be held therein until lifted out by hand.

The door or one of its cross-pieces'will'prevent the bar J from being thrown out by any jolting of the car When'the car is moved with the doorvopen.

The T-rail can be readily and easily se'- cured to the eaves-board, and'` it holds the hangers E from twisting when the door is moved sidewise on the hangers into the doorway. Owing to its T shape the rail D can be made light and yet be sufficiently strong. IVhen the door is made to be pushed in iush or nearly iiush with the side of the door, it willv be bound against the stops m m on the door-post by the locking-bar J, the lockingbar'having its hinged joint-piece adjusted as to.. length to give the desired pressure against the side of the closed door.`

What I claim as new, andV desire to secure by Letters Patent, is-

3. In a freight-car, the combination, with a door-post having a socket a and a sliding door movable sidewise on its supports and having its edge rabbeted and provided With recesses and with a plug c, of the guides G G, secured to the door-post and projecting outward and toward the door-opening to engage the recesses in the edge ot the door, substantially as described.

4. In a freight-car, the combination, with a sliding door, of a locking-bar attached to the side of the car by means of a'hinge Il and having a hinge-joint t', located adjacent to the rear edge of the door at a distance from the hinge I', whereby said bar is capable of being swung in front of the door for locking the same and against the side of the car behind the plane of the door to permit the door to be moved outward and along 'the side oi' the car, substantially as described.
